The operating system of a wire cutting machine is a DOS system. The CAD function of the DOS operating system is simple, the operation is complicated, the operator is required to be high, and the complicated curved surface parts cannot be processed. The external data exchange can only be through the floppy disk drive, and the identification file format is single. Conducive to the promotion and expansion of processing, and the operation is more difficult, limiting the improvement of work efficiency.
To build a two-way communication bridge between operators and machines, upgrade the DOS system to Windows 98. Windows98 is a DOS-based graphical interface operating system. It not only has the real-time transmission characteristics of the DOS system, but also has a friendly interface and simplifies the user's operation steps.
In addition, it also has an open architecture and data interaction functions. The CNC system developed on its platform not only has good openness, maintainability, scalability, but also supports multi-tasking, multi-type file recognition and computer utilization. The function of the programming file.
After adopting the Windows98 operating system, the hardware structure of the CNC system is basically unchanged, but the DOS mode of Windows98 is utilized for machine control. The use of the Windows 98 operating system not only solves the problems of the new version of CAD software usage and document management, but also implements control in DOS mode, and the higher version of the Win-dows operating system does not have this feature.

Tubing is mainly used to provide oil and gas flow passage during production of oil and gas wells. For flowing wells, due to the large inner diameter of the CASING, the casing is directly used for production. Due to the density difference, pressure drop and expansion, the liquid flows up rapidly, causing the liquid to slip, resulting in the ineffective utilization of the downhole elastic energy. Running tubing with smaller OD and ID during production can effectively solve the above problems by allowing fluid to flow in the tubing. Therefore, running tubing is required during production of flowing wells. The downhole operation and production of flowing well and non flowing well can be completed by using various tools for tubing running.
The basic requirements of the tubing used for workover are: to comply with the safety and economic principles, to meet the technical requirements adopted during well completion, and to meet the requirements for corrosion resistance and operation measures after the well is put into production.
According to the manufacturing process, oil pipes can be divided into seamless pipes and electric welded pipes. Seamless pipe is a kind of forged steel pipe without welding seam, which is made of hot working steel. After pressing, stretching, heat treatment and other processes, it reaches the standard size of oil pipe, forming a seamless oil pipe series. Electric welding pipe is a kind of pipe with a longitudinal weld formed by resistance welding or electric induction welding without filler metal. The welding edges are squeezed together by mechanical pressure, and the standard size oil pipes are reached through heat treatment and other processes, forming a series of electric welding pipes.
